Darin Newsom, a local gas analyst, said there are reasons why gas prices rise and fall.

“A lot of it has to do with the underlying market, the volatility of the underlying crude oil or gasoline markets itself,” he said.

Taxes, refining costs and distribution costs also factor into the equation, experts said. Daily prices can even reflect the amount of inventory at each individual station.

“Maybe they have something that was bought at a higher price, and then all of a sudden the market drops and a couple days later you'll see the local market come down as well,” Newsom said.

Newsom said those stations that have a large inventory of gas purchased at a higher price must sell it at a higher price to make a profit, even if the station across the street is 10 cents lower per gallon.
